Definitions

  • a electrical low-voltage AC connection 36 On the upstream or rear end 8 of the gun body 2 is a electrical low-voltage AC connection 36, on which the primary side of the transformer 32 is electrically connected, a fluid connection means 38 for connecting a hose or pipe pneumatic feeding of coating powder into the upstream end of the powder channel 18, and a Compressed air connection means 40 for connecting one Compressed air line to the compressed air duct 20.
  • This Connection means 36, 38 and 40 can be accordingly Fig. 1 on a rear end face 42 of the Gun body 2 or other parts of the Gun body 2 are located, for example, by the Gun handle 6 can be passed.
  • the threaded sleeve 44 contains a rotary atomizer 46 of the type, for example, from the Patents US-A 5 353 995, DE-A 43 40 441, DE-C 31 01 193 and DE-C 30 02 206 are known, but in one much smaller size.
  • the rotary atomizer 46 has a rotatable rotary body 48, which is rotatably mounted in the threaded sleeve 44.
  • the mouthpiece 14 provided with a compressed air extension duct 53, which leads to the turbine drive 51 and which automatically connected to the compressed air duct 20 when the threaded sleeve 44 on the gun body 2 is screwed on.
  • the threaded sleeve 44 with a Compressed air connection 55 may be provided.
  • the rotating head 50 has a circular outer peripheral edge 56 electrically conductive material, which as High voltage electrode for electrostatic charging of the coating powder.
  • the outer peripheral edge 56 is by a spring-loaded ring contact 58 of the Mouthpiece 14, which on the high voltage electrodes or high voltage contacts 24 and 26 of the Gun body 2 rests with the High voltage generator 30 electrically connected.
  • the outer peripheral edge 56 of the rotary head 50 automatically to the high voltage generator 30 electrically connected when the mouthpiece 14 on the gun body 2 is attached.
